Mode of Action
How Does It Work?
- Insulin allows the entry of blood glucose into the cell of the body.
- Inside the cell, glucose is used as fuel.
- In type 1 diabetes mellitus, the body fails to produce insulin.
- It starts glucose accumulation in the blood and causes high blood glucose.
- Insulin Lispro lowers blood sugars by stimulating glucose uptake by cells, tissue and muscles, by skeletal muscles and fat and inhibits glucose production by the liver.
Interactions
Interactions with other medicines
- Some medicines affect the way Insulin Lispro works or the medicine itself reduces the effectiveness of other medicines taken at the same time.
- Inform the physician about the medicines, supplements or herbals you take or might take to avoid possible interaction.
- You experience low blood sugar if you are taking other medicines to treat diabetes, mental health problems (fluoxetine), medicines for fever and pain (salicylates), ramipril, lisinopril.

- Taking pioglitazone to treat diabetes, be cautious, cases of heart attack and heart failure have been reported.
- Some medicines block the body's response to low blood sugar, so you may not experience symptoms like headache, hunger pangs, sweating, anxiety when the blood sugar drops.
